At the risk of upsetting some folks I'd go so far as to say putting an airlock on a bucket with a plastic lid will tell you nothing.
The seals rarely really seal well even with new lid snapped down. Even if you do get it to really seal... Snapping on that lid is only making it harder for you to open and stir/punch down the cap.
Lay the lid on loosely and drape a towel over it or just leave it off and tie a towell down on top.
Your nose will tell you more about that ferment than an airlock on that plastic lid.
